Abstract : The 7th ERCIM Workshop "User Interfaces for All" builds upon the results of the six previous Workshops held in Heraklion, Crete, Greece, 30-31 October 1995; Prague, Czech Republic, 7-8 November 1996; Obernai, France, 3-4 November 1997; Stockholm, Sweden, 19-21 October 1998; Dagstuhl, Germany, 28 November-1 December 1999; and Florence, Italy, 25-26 October 2000. The vision of User Interfaces for All advocates the proactive realisation of the "design for all" principle in the field of Human-Computer Interaction (HCI), and involves the development of user interfaces to interactive applications and telematic services, which provide universal access and usability to potentially all users. In the tradition of its predecessors, this Workshop aims to consolidate recent work, and to stimulate further discussion, on the state of the art in User Interfaces for All, and its increasing range of applications in the emerging Information Society. This year's event emphasises "Universal Access" and invites contributions on a broad range of topics, including technological applications and policy developments aiming to advance the notion of Information Society Technologies accessible and acceptable by the widest possible end-user population. The requirement for Universal Access stems from the growing impact of the fusion of the emerging technologies, and from the different dimensions of diversity that are intrinsic to the Information Society. These dimensions become evident when considering the broad range of user characteristics, the changing nature of human activities, the variety of contexts of use, the increasing availability and diversification of information, knowledge sources and services, the proliferation of technological platforms, etc. In this context, Universal Access refers to the accessibility, usability and, ultimately, acceptability of Information Society Technologies by anyone, anywhere, anytime, thus enabling equitable access and active participation of potentially all citizens in existing and emerging computer-mediated human activities. The user population includes people with different cultural, educational, training and employment background, novice and experienced computer users, the very young and the elderly, and people with different types of disabilities, in various interaction contexts and scenarios of use. As people experience technology through their contact with the user interface of interactive products, applications and services, the field of HCI has a critical and catalytic role to play towards a universally accessible, usable and acceptable Information Society. Scientific/technological contributions should be on concepts and tools that advance our understanding of, and contribute towards, Universal Access to the new computer-mediated virtual spaces. Areas of interest include, but are not limited to, future and emerging technologies, novel computing paradigms, computer-mediated virtual spaces, architectures and tools, interaction platforms, interaction metaphors, experimental or empirical studies, etc., which bear an impact on the scope of human access to digital content in an Information Society. Applications-oriented contributions may address practice and experience in the application of Universal Access principles in critical domains such as health, education, employment, etc. In this context, this year's workshop encourages contributions that elaborate upon, adopt, apply or validate a Universal Access code of practice in selected application domains. Finally, contributions on policy developments should discuss the impact of non-technological factors, such as legislation, standardisation, technology transfer, etc., on developing a culture for Universal Access in the Information Society for all parties concerned and, in particular, the industry. Policy contributions may cover success stories of the past or lay out prevailing obstacles to be addressed and removed by effective policy interventions.
